v TIRE-BIM.

Specification of Letters Patent.

To @ZZ 'whom may concern Be it known that I, SAMUEL?. MICHAEL, a citizen of the United States, and a resident of Frankfort, in the county of Clinton and .State of indiana, have invented a new and improved Tire-Rim, of which the following is a "full, clear, and exact description.

liy invention relates to a rini adapted to constitute a demouutable rim. and including as a part thereof a quick detaching tireliolding element, whereby to detach the tire Without demountina the riin as a Whole or disturbing; the parte of the rim other than the detachal'ile tire element.

bjects of the invention are to provide av rini having the vmentioned characteristics and so constructed and arranged that the attaching or dctaching of the tire, or the mounting or deinounting of` the rim, may be effected without the use of extra wrenches, without hammering', and with the minimum expenditure of time and Work.

Other objects of the invention are to effect the secure holding of the rim and tire and promote simplicity of construction with the maximum strength and durability.

The invention nill be particularly eX- plained in the specific description 'following'.

Reference is to be had to the accompanyinn drawings forming a part of this specilication in which similar reference characters indicate corresponding parts in all the Views.

Fig. 8 is a cross section on the line 8--8, Fig. 1;

`Fig. 9 is a cross section similar to Fig. 3 but showingT auxiliary tire-holding elements to be employed in the case of a flat-sided tire;

Fig. 10 is a side View ot a portion of one of the said auxiliary elements enteringinto atented July 3.1191-7.

the arrangement illustrated in Fig. 9; and.`4`

Fig. 11 is an enlarged transverse section on the line 11-11, Fig. 10. i

My improved rini is formed Aof separate side sections'7 10, 11, having, respectively, annular tire-engaging` members, 12, 13, which, generally, will `be elena-her nienibers.V

The opposed edges of the respective seetions interlock by means of alternate projections and recesses, there beingr laterall projections 14 on the one section and matins;y projections 15 on the opposed edge of the oppositesection, the projections on one section being receivable in the recesses of the other. l

The respective rim sections 10, r11, have co-actingifastening' elements so that Vone rim section will constitute a quick detaching tire element for quickly removing a. tire Without disturbing the rim as a Whole. For the mentioned purpose the section 10 is provided on certain of the projections 14 thereof with bolt extensions 16 ot a vlength to extend .through the clamp flange '17 on the opposed section 11, the connection being' completed by a nut 18. The tightening up of a nut.

draws the clencher elements, 12, 18, toward each other to securely retain a tire B in position.

At the inner side of the rim, a known form of clamp ring' 19, or other approved detachable rim clamping means is employed to engage the rim at that side. The form of clamp ring illustrated is provided with an inwardly disposed annular wedfje flange 2O to enter beneath the riin, between the samevand the telly A, and also, sail ring 19 is Jformed with a curved {iange :Zito engage the rirn section 10. Atthe opposite side cvo f the rim there is formed on the said rim seetion 10 lateral extensions 22, having lugs Q3 extending radially inward ot said extensions. It will be observed that the lugs 23 are disposed at the same side of the rim as the bolts 16 and the (zo-acting clamp flange 17 of the detachable rim section 11. A series of transverse bolts 24 extend through the telly A, through the lugs 23, and through lugs 26 on the ring 19 at the opposite side of the telly, nuts serving to complete the clamping ot the rim to the telly. It will be seen that the bolts 24 thus serve to demonntably secure the rim 'lo the lessees :telly independently of the belts l@ that conneet the rim sections l0, il, with erich other. ln'prectice, therefore, by merey loosening Vthe nuts 18, kthe rim section 1l may bc quickly detached to remove the tire B,

4radially outward from tile-odset bolts i6 and the oi'set extensions 22. it is to be noted also, that the described construction permits of the nuts and i8 being located et the seme side of the Wheel, that is to eey,

et the outside end that the :1eme wrench may be employed to ytighten or remove the nuts, the unscrewing oie, few nuts heilig eil tirait 1s necesssry to permit the detachment .ofnthe rirn section 11 end the rei'riqvel of the nuts 25 end bolts? 2i alone being required to remove the rim as e. whole.

in order toy enable improved rim to lbe employed with e flat-sided tire in cese of necessityJ provide, es shown in Fig. 9, od-

ditionei ennuier elements v246 having *dat` innerlsides and having beads 27 on the outer sides monding in cross section to conform to the concevity of the ciencher members,

13. The elements 26 are mede up in detachable segments, having e; slot and pin lconnection et their ends there beine a slot the side edges thereof, the seid beveling also preventing buckling of the rim.

i would mention that my improved rim is adaptable for use with e solid tire, theref by making the rimKsuitable' lfor use on trucks, as entre; tires con be readily carried Ves With others having ordinary rims.

Hoving thus described my invention l i claim as new end desire to secure by Letters Patent: Y

lA tire hoiding rim. for vehicle Wheels, comprising two annuler sections of substantialiy the seme diameter and heving abutting edges, members on one section extend ing vfrom the abutting edge thereof under the other section and having inwerdlyapro `ectinde ertured extremities. and ineens for securing' the sections together.

2. A tire rim composed of annular side sections formed et the outer sides thereof With annular tire-hoiding members, the opposed edges of the seid sections having Inetng lateral tongues end recesses, the transverse edges of seid tongues and recesses being dove-teiied, and means to detachebly connect the sections. Y

3. A tire-holding rim for vehicle wheels comprising two annuler sections ovsubstmitially the seme diameter and having abutting edges, the members on one sect-ion ex tending from the abutting edge thereof under the other section and having inwardly projecting apertured extremities,ndditionnl `members on thesame section carrying the first-mentioned members, and nwerdiycxtending members on the other section engaged with the second-mentioned members. in testimony whereof hnve signed my nemel to this specification in the presence of two subscribing witnesses.
